The tube-type rheometer was used in this experimental study, and the sewage was treated as homogeneous non-Newtonian fluid. In addition, the relational expression between viscosity parameters was developed, and the function of apparent viscosity was obtained. It is concluded that the viscosity characteristic of sewage is influenced largely by complex mixture in sewage, and the sewage has the characteristic of sheared densification fluid.展开更多

Following J M Davis’s Works, semi-solid medium was usedfor initial cloning. Five of them were studied further. Their main chromosome- numbers range were 96 to105, all of them were IgG1 subclass. The affinities of these McAbs were estimated to be 1. 25 ×108 mol/L, 1. 12×108 mol/L, 2. 34×108 mol/L, 8. 55 × 107 mol/L, 1. 04×108 mol/L, respectively.Two groups of mice challenging with E Coli (107 organisms), one group treated with 2mg/kg anti-TNF monoclonal antibody, the other did not. There was a higher survival rate in treated group, the serumTNF level was significantly lower too, and the untreated mice had severe pathologic changes in vlscera.展开更多
